ARTICLE 3º - Refereeing

The mat referee is the highest authority on the mat and has the authority to disqualify competitors during the match. No one can overturn his decision. In special cases the CBJJ Confederation can review and overturn a referee’s decision if the decision is unjust. The referee is assisted by the time keeper in the matches. In cases where a referee shows himself incapable to continue refereeing because of obvious mistakes, the inspector of the event has the authority to replace him.

During the match the central referee is to always be directing the competitor to the center of the ring. In the event that the competitors move out of bounds during the match, the referee will call "PAROU" and at the same time the referee will do the gesture according to the command, and the competitors must hold their position without movement. The same occurrence will happen when 2/3 of the competitor’s body is outside the boundary. The referee may be assisted by the timekeeper in moving the athletes back to the center of the ring. In case the referee and the timekeeper are unable to move the athletes back to the center of the ring, the athletes will be asked to walk back to the center and continue from the same position.

The referee will not allow interference from outsiders during the match. Medical team or nurse will be allowed on the mat at the referee’s discretion.

During the match, the referee or persons at the scoring table are not allowed to converse with the competitors, this will be strictly enforced.

Expiration of time will be determined by the timekeeper during the match. The timekeeper will notify the central referee immediately with an auditory and visual signal.

After the table gives the signal whistle, that the match is over, the referee can give an advantage point to the combatant for attempting a submission or for attempting to establish a dominane position without maintaining for the required time, except for take-downs because athletes don't need to establish a dominenet position to award points.

The judges table will actualize the referee’s gestures on a scorecard. The table will have two official score scoreboards with green, yellow and white cards for scoring the points and advantages.

Notes taken are the responsibility of the scorekeepers. Notes may not be altered and must read exactly what the central referee dictates and cannot be altered.

OBS: According to Confederation Of Brazilian Jiu Jitsu regulations there will be 3 referees per ring. When a match is in action, the criteria are as.following.

1. The side referees have equal authority as the center referee. This
   means all 3 referees can call points and advantages as well as punishments.
2. Awarding points and/or punishments will be based on two referees
   against.one-“majority..rule”.
3. In the instance that the three referees are divided on a call, the
   decision will fall in the center of the three calls.
   

   EX: The center referee awards 3 points for guard pass, one of the side referees awards an advantage while the other side referee awards no points. The call we be advantage, because that is the decision between the two extremes.

Important: Any and every situation that can not be determined by the manual will be left up to the referees discretion.
